Hoya acuta is a charming and fast-growing tropical vine admired for its glossy green foliage and clusters of star-shaped, fragrant flowers. A member of the Apocynaceae family and native to Southeast Asia particularly Thailand, Malaysia, and the Philippines this species is a perfect balance of ornamental leaves and showy blooms, making it a favourite among Hoya enthusiasts.
The leaves are smooth, slightly elongated, and medium to dark green with a leathery texture and subtle venation. Under bright light, they may develop soft red or bronze tinges around the edges. Mature Hoya acuta plants produce spectacular umbels of creamy white to pale pink flowers with a crimson corona at the centre. Each cluster can hold dozens of blooms that emit a rich, sweet fragrance especially noticeable in the evening.
Delicate yet vigorous, Hoya acuta offers the classic Hoya appeal in an easy-care form a rewarding addition for collectors and beginners alike.
Thrives in bright, indirect light. Provide several hours of soft morning or filtered sunlight each day to encourage flowering and healthy leaf colour. Avoid harsh, direct sun, which can scorch the leaves, and low light, which may prevent blooming.
Allow the top 35 cm of soil to dry between waterings. Water thoroughly and let excess drain away Hoyas dislike wet feet. In winter, reduce watering slightly while maintaining moderate humidity. Overwatering is the most common cause of root rot.
Temperature: Prefers warmth between 1830 C. Avoid temperatures below 15 C.
Humidity: Moderate to high humidity (5080%) is ideal. The plant tolerates average indoor levels but will thrive and flower more readily in slightly higher humidity.
Use a light, airy, and fast-draining mix a blend of orchid bark, perlite, coco coir, and a small amount of compost works well. This mimics the plants natural epiphytic habitat. Hoyas prefer to be slightly root-bound, so only repot every 23 years in spring to refresh the soil.
Feed every 46 weeks in spring and summer with a diluted, balanced liquid fertiliser or one formulated for flowering plants. Reduce or stop feeding during autumn and winter when growth slows.
Trim long or leggy vines to shape the plant and encourage bushier growth. Avoid removing the short flower spurs (peduncles) Hoya acuta reblooms from the same spurs each year. Wipe leaves gently with a damp cloth to remove dust and highlight their natural gloss.
A moderately fast grower, Hoya acuta can reach 1.52 metres in length when allowed to trail or climb. When trained up a trellis or hoop, the plant develops a fuller form and produces more frequent flower clusters. With the right light and care, mature plants can bloom several times per year.
No flowers: Insufficient light or repotting too frequently.
Yellow leaves: Overwatering or poor drainage.
Wrinkled leaves: Underwatering or prolonged drought.
Pests: Occasionally affected by mealybugs or spider mites treat with neem oil or insecticidal soap.
Native to the humid rainforests of Southeast Asia, Hoya acuta grows epiphytically, clinging to trees with its roots while absorbing moisture from the air. Its fragrant blooms and vigorous growth make it one of the more rewarding Hoyas to cultivate.
In addition to its ornamental beauty, Hoya acuta symbolises patience, friendship, and enduring affection qualities often associated with the long-lasting, fragrant clusters of Hoya flowers. Like many Hoyas, it also helps purify indoor air, improving air quality in homes and offices.
